OBJECTIVE
Pancreatic neuroendocrine tumors expressing serotonin (carcinoid tumors) account for a small portion of pancreatic neuroendocrine tumors. The purpose of this study was to describe cases of small serotonin-producing pancreatic neuroendocrine tumors associated with pancreatic duct obstruction.
CONCLUSION
Serotonin produced by pancreatic neuroendocrine tumors can induce fibrosis and pancreatic duct obstruction. Pancreatic neuroendocrine tumors should be considered when CT shows a small hypervascular mass associated with upstream pancreatic duct dilatation or atrophy. Evidence of small pancreatic neuroendocrine tumors should be sought in cases of idiopathic pancreatic duct stenosis.
目的
表达血清素（类癌肿瘤）的胰腺神经内分泌肿瘤占胰腺神经内分泌肿瘤的一小部分。本研究的目的是描述与胰管阻塞相关的小型血清素产生胰腺神经内分泌肿瘤的病例。
结论
胰腺神经内分泌肿瘤产生的血清素可引起纤维化和胰管阻塞。当 CT 显示与上游胰管扩张或萎缩相关的小血供性肿块时，应考虑胰腺神经内分泌肿瘤。在特发性胰管狭窄的情况下，应寻找小型胰腺神经内分泌肿瘤的证据。
